• Description:

  AN AFFORDABLE POWERHOUSE!
  What will you do with 461 horsepower and 558 lb.-ft. of torque from Chevrolet Performance's value-driven 502 HO crate engine? Whether you use it on the street, strip or even pulling a trailer with your workhorse truck, its performance range offers unlimited possibilities. In fact, it makes nearly 500 lb.-ft. by only 1,500 rpm, meaning it has all the low-rpm grunt you can use!
  To support all that torque, we build this Big-Block with our latest-generation block casting with four-bolt main caps and complement it with an all-forged rotating assembly for exceptional strength and durability. A hydraulic roller camshaft is used for excellent drivability and a broad performance range; and an 8.75:1 compression ratio is suitable for regular pump gasoline at all altitudes and engine loads.
  Our crate engine assembly includes an aluminum, dual-plane intake manifold, a water pump, 14-inch flexplate, balancer and more. You add the carburetor, starter and ignition system - all available from Chevrolet Performance.
